Sketch 49 changed the way Artboards export their content. This means that if you have a large Artboard with smaller Artboards placed on top of it, you can no longer export the background Artboard to save all your Artboards as a single image. To do this in Sketch 49, you must now create a slice layer to export all the content within.

Although Sketch doesn’t always require you to be connected to the internet it does sometimes need to connect to a network, for example when you register your copy of the app, or when Sketch needs to validate your license.

Your feedback is valuable to us, and we appreciate the time spent getting in touch. If you have found a bug, crash, or have any problems with Sketch, then including an attachment with your report will help us diagnose your issue quicker.

If you are using plugins with Sketch, you may come across certain issues that are caused by them. Please make sure you keep your plugins up-to-date, and if that doesn’t fix your issue, please contact the plugin author. Plugins are created by third-party developers and we are not responsible for their stability.
